What we'll cover:
When you’re shopping for a savings account, the first thing that grabs your attention is probably the interest rate.
After all, interest rates can help give you an idea of how much you could earn from your deposits over time. Generally speaking, the higher the rate, the more you could earn.
But have you ever wondered how interest rates are determined in the first place? Who’s the proverbial hall monitor?
While interest rates can go up or down for a number of complex reasons, the Federal Reserve (or simply, the Fed) has a great deal of influence over them. That’s why whenever the Fed makes its rate announcement, the financial world hangs on to every word.
Remind me, what does the Fed do? The Federal Reserve is the central bank of the United States. It’s tasked with the important job of maintaining a stable economy by implementing monetary policies to promote maximum employment and stable prices.
In other words, the Fed works to make sure the US economy doesn’t run too hot (long period of growth with high inflation) or too cold (not enough growth).
The “rate” we’re talking about here is specifically the federal funds rate, which can influence the interest rates that banks offer across various deposit accounts, like a high-yield savings account or certificate of deposit (CD).

In the simplest terms, the federal funds rate is the interest rate that banks charge when they lend money to each other overnight. (Yes, banks borrow money, too. Usually it’s to help them meet their reserve requirements.)
The federal funds rate is set by the Federal Open Market Committee (FOMC), the monetary policymaking arm of the Fed. It meets about eight times a year to discuss and announce new target rates.
The federal funds rate is typically expressed as a range. For example, when the FOMC met in September 2025, the committee announced a target range of 4.0%-4.25%.
Earlier we mentioned that the Fed’s job is to keep the economy stable.
To carry this out, the Fed has to keep an eye on inflation (among other things) and make monetary adjustments as necessary to keep it in check.
How do they do this? One way is by adjusting the federal funds rate.
Here’s a high-level overview of how it works:
To be sure, there are more nuances to this. But for the purpose of this article, we’ll spare you the full-on lecture on monetary policy.
Let’s keep things moving and talk about how changes in the federal funds rate could impact your savings.
If you look up the federal funds rate, you may be thinking, “Hey, this isn’t the rate I have on my savings account, what gives?”
It’s important to understand that banks look to the federal funds rate only as a guide—not as a rule. Banks are not required to line up their interest rates with the Fed’s rate. So each bank will respond to the Fed’s rate announcement and adjust rates in their own way.
That being said, when the Fed raises the federal funds rate, banks tend to increase the rates they offer on deposit accounts. On the flip side, when the Fed cuts rates, banks tend to reduce their rates as well.
However, banks don’t always have to wait for the Fed’s announcement to make a move. Sometimes, the anticipation of a rate change is enough to spur banks to increase or decrease their rates for customers.
A friendly reminder: Keep in mind that rate changes may only impact certain existing accounts.
For instance, if you have a deposit account that offers a variable rate (like a high-yield savings account), you’ll likely see a rate change in your account when the Fed lowers its rate.
On the other hand, some deposit products come with a fixed rate (such as fixed-rate CDs). When the Fed changes its rate, if you already own a CD, your existing fixed rate won’t be affected for the term of your CD.
Now that you understand why interest rates can change from time to time – you may be wondering how Marcus thinks about rate changes.
Great question.
Our team of experts puts a lot of thought into finding the right rates for our customers. Our primary goal is to consistently offer highly competitive rates across our deposit products, including our Online Savings Account and CDs.
To do this, we consider three key variables:
Let’s take a moment to talk about the expectation of the federal funds rate. Because when Marcus thinks about rates, not only do we look at the current federal fund rate, we also consider how the Fed is thinking about its rates moving forward.
Now, we don’t have a crystal ball. But here’s the thing: Even if the Fed doesn’t announce a rate change, they often signal how they might adjust rates in the future.
Our team at Marcus, along with our colleagues at Goldman Sachs, pays close attention to the Fed and other key developments in the economy.
Together, we put our expertise to work for our customers—to determine the right rate for you and share key insights about the rate environment.
At its April meeting, the FOMC left the fed funds rate unchanged at 3.50%-3.75%.
Fed Chair Jerome Powell repeated the message from the March meeting that the FOMC can “wait here and see.” In his press conference, Chair Powell noted that the committee had a “vigorous discussion” about the policy guidance.
He said that the number of FOMC participants who could support moving to balanced guidance has increased since March and that the center of the FOMC “is moving toward a more neutral” outlook for future rate changes. But a majority of participants, he noted, felt making a change now was unnecessary.
Goldman Sachs Research sees the widening support on the FOMC for shifting to balanced guidance as mostly connected to the upside risks to inflation introduced by the war. But it’s also likely true (and it was already clear before the April meeting) that some FOMC participants would likely hesitate to cut in a scenario where the war is over but inflation remains closer to 3% than 2%, even if most of the overshoot comes from tariff and energy passthrough.
Goldman Sachs Research continues to expect rate cuts in September and December and sees the risks around their Fed forecast as tilted toward a longer pause rather than rate hikes.
While it’s hard to predict the future, we hope to encourage you to continue to save and work toward your financial goals.
